REVERSIBLE RAIL-G RIP FOR BEDSTEADS.

SPECIFICATION forming part of Letters Patent No. 605,286, dated June 7, 1898.

Application filed October 26, 1897. Serial No. 656,476. (No model.)

To aZZ whom it may concern:

Be it known that I, GEORGE BRAND, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented a certain new and useful Reversible Rail-Grip for IronBedsteads, of which the following is a specification.

' face of said member, while the second member of the joint has wedge-shaped portions entering between said bearing-surfaces and the abutting face, whereby all rocking motion in the joint is prevented. In thepresent in- I vention the purpose is to construct a joint in which this same rigidity and perfection of union shall exist and which at the same time will allow of the reversal of the main portion of the rail.

To this end the invention consists in the formation, construction, and combination of I in the claim.

parts hereinafter fully described,and set forth In the accompanying drawings, which form a part of this specification, Figure 1 represents in perspective the two parts of my improved rail-joint separated. Fig. 2 is a partially-sectionized side elevation of said parts, and Fig. 3 is a side elevation of said parts with the main portion inverted.

The purpose of having the main portion of the rail reversible is for the accommodation of different forms of spring bed-bottoms.

The form of. rail best adapted for reversal is what is known as the angle-rail, (represented in the drawings at 4.) In the usual constru ction of an iron bedstead a suitable length of angle-iron bar has cast upon its ends the removable portions of the rail-joint, one such portion being indicated at 5.

It is at present the custom in making spring bed-bottoms for iron bedsteads to allow the end piece to project beyond the side rails so as to rest upon the rails of the bedstead; but

spring bed-bottoms designed for wooden bedsteads do not have these projecting end pieces and are not, therefore, adapted to iron. bedsteads. i It is also usual in the construction of the removable side rails to place the broad is indicated in position in broken lines at 6 in Fig. 3. In making the removable side rails reversible this broad portion of the side rail may be placed at the underside, as indicated a in Figs. 1 and 2, and when so placed any of the ordinary forms of bed-bottoms constructed for wooden beds may be readily placed upon this broad side of the rail, as indicated in broken lines at 7 inFig. V2.

Having now disclosed the object of making the side rails reversible,the special construction of the slip-joint by which this reversibility is allowedand the perfection'of the joint maintained will be described.

' That portion of the rail-joint containing the socket and which is here shown adapted for attachment to or support upon the head or foot board of a bedstead is indicated at B and is substantially the same construction as that shown in the patent above referred to. It has the wedge-shaped portions 9, formed by the outer face of the part 8 and the inner wall of the socket. The T-head 10 upon the part 5 has upon the side facing'the end of part 5 central bearing-surfaces 11, which, as indicated in Figs. 2 and 3, engage the inclined surface of the wedge portions 9 midway of their length, and in that manner make a bind ing connection between the abutting faces of the two parts 5 and 8.

The heads 10 have the greatest diameter in the plane of the bearing-surfaces and taper equally in both directions therefrom, so that no matter which end of the head 10 enters the socket the central bearing-surfaces will come to the same point on the wedge-shaped. portions 9 and bring the part 5 in close union with the part 8 and so as toleave the upper surfaces of said parts flush with one another.

It will'be noted in this j oint,as in that of the patent referred to, that ample clearance is allowed between the rear wall of the socket and the outer wall of the head 10, so that any fins or roughness upon either of these surfaces will in no wise affect the union of the parts,and inasmuch as the head engages the socket at only the central bearing-surfaces the only parts of the joint in which especial accuracy I in construction must be obtained are the central bearing-surfaces and theplaces on the wedge-shaped portions with which they enage. I a 'lhe abutting faces of the members of the joint may be perfectly plane, as indicated in Figs. 1 and 2, or one or both of them may be cut out somewhat intermediate of the upper and lower edges, as indicated at 12 in Fig. 3 and as shown in said patent. This construction further facilitates the production of a rigid and stable connection between the parts of the joint;

While I have described in detail the T-head and socket of special construction and one which I believe best adapted for use in a reversible rail for bedsteads, I do not limit myself to this special construction of these parts,

since they may be varied, and yet the reversibility of the side rail obtained, The main portion 4 of the side rail may also be of different construction, and yet allow of the attainment of the ends specified.

What I claim as my invention is- A slip-joint consisting of the members 5 and 8, the former provided with a head 10, having central bearing-surfaces from which the head tapers toward each end and a face abutting
